Answer:4.9mph per meter

Explanation:

The weight of a person on the moon given that the mass of the person on Earth is 105 lbm is 17.3 lbf.

Force is defined as the influence that produces a change in motion of an object. The unit of force is newton (N), which is defined as the amount of force that can accelerate a mass of 1 kg at a rate of 1 meter per second squared (m/s²).

The weight of an object is the gravitational force acting on the object. It is directly proportional to the mass of the object and the acceleration due to gravity. The unit of weight is newton (N).

Formula to calculate weight:

Weight (N) = mass (kg) × acceleration due to gravity (m/s²)

Conversion from lbm to kg:1 lbm = 0.453592 kg

Acceleration due to gravity on the moon is 1.622 m/s².

Therefore, Weight (N) = mass (kg) × acceleration due to gravity (m/s²)

Weight on Earth = 105 lbm

= 47.63 kg

Weight on Moon = 47.63 × 1.622

Weight on Moon = 77.19 N

= 17.3 lbf

Therefore, the weight of a person on the moon given that the mass of the person on Earth is 105 lbm is 17.3 lbf.

Answer:

The horizontal component of the velocity is approximately 42.6 m/s

Explanation:

The given parameters are;

The speed of the arrow when it was shot = 52 m/s

The angular direction in which the arrow was shot, θ = 35° above the horizontal

The horizontal component of the velocity is found by the resolution if the velocity vector into its components as follows;

The horizontal component of the velocity = Velocity in the x-direction = vₓ

vₓ = v × cos(θ) = 52 × cos (35°) ≈ 42.6 m/s

vₓ = The horizontal component of the velocity ≈ 42.6 m/s

The average speed of the ball is 0.15 m/s.

The average speed of the ball can be calculated using the formula below.

Answer:  Force per unit area. Explanation: P = 25/20. P = 5/4 Pascal or 1.25 Pascal

Explanation: is this what you were looking for

The total binding energy for 19578Pt is approximately \(1.094 \times 10^(^-^1^1^)\)Joules, and the binding energy per nucleon is approximately\(5.6 \times 10^(^-^1^4^)\) Joules.

To calculate the total binding energy (BE) and binding energy per nucleon (BE/A) for 19578Pt with an atomic mass of 194.964774 u, we need to use the mass defect concept and Einstein's mass-energy equivalence equation (E = mc²).

First, we calculate the mass defect (∆m):

∆m = \((Z \times mp + N \times mn) - m(atom)\)

Where Z is the number of protons, mp is the mass of a proton (1.007276 u), N is the number of neutrons, mn is the mass of a neutron (1.008665 u), and m(atom) is the atomic mass.

For 19578Pt:

Z = 78

N = 195 - 78 = 117

∆m =\((78 \times 1.007276 + 117 \times 1.008665) - 194.964774\)

∆m = 0.1215 u

Next, we calculate the total binding energy:

BE = ∆m \(\times\)c²

Using the speed of light,\(c = 3 \times 10^8\) m/s, and converting u to kg:

BE = (0.1215 \(\times\)1.66053906660 x \(10^(^-^2^7^)\) kg) \(\times\)(\(3 \times 10^8\) m/s\()^2\)

BE =\(1.094 \times 10^(^-^1^1^)\) Joules

Finally, we calculate the binding energy per nucleon:

BE/A = BE / (Z + N)

BE/A = (1.094 x \(10^(^-^1^1^)\) J) / 195

BE/A =\(5.6 \times 10^(^-^1^4^)\)J

Therefore, the total binding energy for 19578Pt is approximately\(1.094 \times 10^(^-^1^1^)\) Joules, and the binding energy per nucleon is approximately \(5.6 \times 10^(^-^1^4^)\) Joules.

Voltage is the change in electric potential so basically current flows from high potential to low potential due to voltage.

Perceptual errors, cognitive biases, and emotions can indeed have negative effects on negotiations. Here are three examples illustrating each:

1. Perceptual error: One common perceptual error is the halo effect, where an overall impression of a person or situation influences the perception of specific attributes or qualities. In a negotiation, I may have made the mistake of perceiving my counterpart as more competent and trustworthy due to their confident demeanor and well-dressed appearance. This perceptual bias may have led me to underestimate their true intentions or overlook potential risks.

2. Cognitive bias: Confirmation bias is a cognitive bias where we seek and interpret information in a way that confirms our pre-existing beliefs or expectations. During a negotiation, I might have had a confirmation bias that my proposed solution was the best option. As a result, I might have selectively paid attention to information that supported my viewpoint and dismissed or ignored evidence that challenged it. This bias could have hindered open-mindedness and prevented me from considering alternative solutions.

3. Emotion: Emotions play a significant role in negotiations and can impact decision-making. For example, I might have experienced strong frustration during a negotiation due to the slow progress and lack of cooperation from the other party. This emotional response could have impaired my ability to think rationally and objectively, leading to impulsive or aggressive behavior. It might have also hindered effective communication and collaboration, potentially damaging the negotiation process.

In negotiations, it's important to be aware of these potential pitfalls and actively work to mitigate their effects. Developing self-awareness, practicing empathy, seeking diverse perspectives, and employing logical analysis can help counteract the negative impact of perceptual errors, cognitive biases, and emotional responses.

According to the contemporary model of electric charge, the explanation that agrees is option (f)b and d .f) If an object is charged negatively by rubbing, it has acquired negatively charged particles .(b) If an object is charged positively by rubbing, it has lost negatively charged particles.

The contemporary model of electric charge is based on the concept of the conservation of charge. It states that charge is neither created nor destroyed but can be transferred from one object to another. When two objects are rubbed together, the transfer of charge occurs.

When two objects are rubbed together, electrons can be transferred between them. Electrons have a negative charge, so if an object gains electrons during rubbing, it becomes negatively charged. This corresponds to option (f): If an object is charged negatively by rubbing, it has acquired negatively charged particles.

On the other hand, if an object loses electrons during rubbing, it becomes positively charged. Since electrons have a negative charge, the object being rubbed loses negatively charged particles. This aligns with option (b): If an object is charged positively by rubbing, it has lost negatively charged particles.

Therefore, both options (f) and (b) correctly align with the contemporary model of electric charge.

Both statements are false.    Search for a graphic of the "electromagnetic spectrum."  Many will note the wavelengths of the various regions (IR, UV, Visible, Microwave, etc.  Observe the relationships.  Red has less energy than blue.  That sounds counterintuitive, based on artist's use of red to connote fire or some energetic situation.  But the red in a fire obscures human vision to the blues and UV radiation from the same source.  A welder uses a UV shield to blocjk these wavelengths, to avoid eye damage.

Answer:

(D) is visible light

Explanation:

(F) is xray and (B) is radio

The answer is (a) F=60.8N, θ=34.7 degrees.

The laws of vector addition include:

Commutative law:  a + b = b + a.

Associative law: (a + b) + c = a + (b + c).

Distributive law: a(b + c) = ab + ac.

Additive identity: a + 0 = a.

Additive inverse: a + (-a) = 0.

To solve this problem, we can use the laws of vector addition. We can start by breaking down each force into its x and y components:

f1x = 30.0 N cos(0) = 30.0 N

f1y = 30.0 N sin(0) = 0 N

f2x = 40.0 N cos(60) = 20.0 N

f2y = 40.0 N sin(60) = 34.6 N

The x-component of the resultant force is the sum of the x-components of the two forces:

Fx = f1x + f2x = 30.0 N + 20.0 N = 50.0 N

The y-component of the resultant force is the sum of the y-components of the two forces:

Fy = f1y + f2y = 0 N + 34.6 N = 34.6 N

The magnitude of the resultant force can be stated by the Pythagorean theorem:

F = sqrt(Fx^2 + Fy^2) = sqrt((50.0 N)^2 + (34.6 N)^2) = 60.8 N

The direction of the resultant force is given by;

theta = atan(Fy/Fx) = atan(34.6 N/50.0 N) = 34.7 degrees

Velocity is the pace and direction of an object's movement, whereas speed is the time rate at which an object is travelling along a path. In other words, velocity is a vector, whereas speed is a scalar value.

For instance, 50 km/hr west denotes the velocity of a car whereas 50 km/hr (31 mph) denotes the speed at which it is moving down a route.

The average speed of an object is determined by dividing the distance traveled by the amount of time it takes the object to reach the distance.
